When I used the example of the true story about a man's experience with jobs, I am not saying his problem is your problem, what I am saying however is that this man genuinely did not KNOW his problem until that one boss decided to tell him the "why".

You have decided that you have been "rejected" but that is you deciding the reason instead of you seeking out these teachers and asking them "why" you were passed over despite all the effort you put in to this activity. Remember that you are still just "learning" and part of that includes asking verses running away with how you feel which as you have shared is "rejected". As you are now noticing it is this emotion that is disrupting your efforts towards embracing learning other subjects.

Also, one of the things I have noticed in my life is how educational ideals are NOT necessarily a true judge of "the best or most worthy". This fact has led to many who develop a take away message of "being rejected". When I think about this, one of the things I think about is how a mere bagger at a grocery store noticed how the way bagging was being done was not proficient and he created something he felt would make this so much easier. Well, as a result this bagger is now a millionaire. This individual was not considered all that intelligent and he did not have that coveted education either.
